Introduction
|
|
============
|
|
|
|
VapourSynth is an application for video manipulation. Or a plugin. Or a library.
|
|
It's hard to tell because it has a core library written in C++ and a Python
|
|
module to allow video scripts to be created. It came to be when I started
|
|
thinking about alternative designs for Avisynth and most of it was written
|
|
over a 3 month period.
|
|
|
|
The software has been heavily inspired by `Avisynth <http://www.avisynth.org>`_
|
|
and aims to be a 21st century rewrite, taking advantage of the advancements
|
|
computers have made since the late 90s.
|
|
The main features compared to Avisynth are:
|
|
|
|
* Multithreaded - Frame level multithreading that scales well
|
|
* Generalized Colorspaces - New colorspaces can be specified at runtime
|
|
* Per Frame Properties - Additional metadata can be attached to frames
|
|
* Python Based - The scripting part is implemented as a Python module so you
|
|
don't have to learn a special language
|
|
* Support for video with format changes - Some video just can't stick to one
|
|
format or frame size. VapourSynth can handle any kind of change
|
|
* Compatible with a large number of already existing Avisynth plugins

the author was to try to improve Avisynth, the software that once made him

interested in video editing. VapourSynth is the result of all that time waiting.
